carcinoma is a unique type of extrahepatic adenocarcinoma with a significant component or entire tumor showing hepatocellular differentiation.
Histopathology diagnoses were squamous cell carcinoma (three cases), basal cell carcinoma, perianal mucinous adenocarcinoma, hepatoid
carcinoma, and apocrine carcinoma with squamous differentiation.
These cells were hepatoid
in appearance, with distinct cell borders and abundant, deeply eosinophilic to basophilic, finely granular cytoplasm.
Among the topics are neoplastic mimics common to the entire gastrointestinal tract, neoplastic mimics of the serosa and mesentery of the gastrointestinal tract, hepatocellular or hepatoid
neoplastics mimics of the liver, vascular neoplastic mimics of the liver, the gallbladder and biliary tree, and the pancreas.
Androgen receptor expression in normal, hyperplastic and neoplastic hepatoid
glands in the dog.
Other exocrine cancers include adenosquamous carcinomas, signet ring cell carcinomas, hepatoid
carcinomas, colloid carcinomas, undifferentiated carcinomas and undifferentiated carcinomas with osteoclast like giant cells.
Three types of glandular tumors like perianal or circumanal or hepatoid
tumor, apocrine gland tumor of anal sac and apocrine gland tumor commonly occur in perianal area of canines (Parry, 2006).
adenocarcinoma of the renal pelvis producing alpha-fetoprotein of hepatic type and bile pigment.
The histopathologic type of gastric carcinoma include well and poorly differentiated adenocarcinoma, hepatoid
adenocarcinoma and denososquamous carcinoma.
This tumor has different histologic patterns: typical (reticular, solid, papillary, parietal), polyvesicular, hepatoid
, glandular, and mixed.
4) Almost always a unilateral solid or partly solid and cystic tumour, displays a wide range of histologic patterns like microcystic, endodermal sinus, solid, alveolar-glandular, papillary, myxomatous, macrocystic, hepatoid
, primitive endodermal or polyvesicular vitelline.
